Here's Why You Need an LSD: th-cam.com/video/qMMvuTb5G1M/w-d-xo.html
I love this build so much kern thank you for all the support with installs and details you give on parts for our platform.
youre the gold standard of B58 videos
Thank you for showing all details of this replacing work.
Your install videos are super straight forward and helpful. Thank you 💪🏽
Great work dude! Can't wait to hear your impressions
I want this upgrade, great vid kev! thank you as always
Been NEEDINGGGGG this video thank you so much. I've had a f30 340 for 2 years now and after a couple track days this is definitely the one upgrade this car is in need of.
it makes the car so much faster through turns. highly recommended
Just started thinking about the m lsd for my 6mt 340i yesterday. You’re a mind reader man
I had this mod on my 2015 335i and it was game changer. This made the car so fun before I moved to my M340i :-) Best mod
I been waiting for this one for a minute!!!
Thank you a lot. I will do it on mine next week.
Love from Germany ❤️
glad to help
Man you made it seem so easy. Took my friends and I all day to install the LSD on my car a few months ago
Definitely took me longer than the video shows haha
hhhhh😂
this is a good tutorial that not a lot of ppl are willing to put out. if you make more than 500whp in one of these cars, this is the first mod you should be doing!
Anything above 300 whp lmao
@Starscream8896 uhhh.. whos gunna tell this guy the stock hp output to the 340i...
Great vid. Can't wait for the xdrive version. 19 440i xdrive here.
Also, down for a jacking your up video 😆 🤣 😂
new music freestye at the end, cool
surprised this differential does not connect to any sensors or something electronic, just a swap
will be looking forward the other video you mentioned about the differences and the benefits (pros/cons)
Kern good you went for the M-Performance plated diff. I installed and OS GIKEN LSD on my M140i 4 months ago. Hands done the best mod I have done to my cars. Guys do you self a favor if you go for an LSD always take a plated one. It makes the car so much more predictable. All those torsen ATB diffs are better for FWD.
you going to love this.
already do
@@kern417 daamn i think i need to order a manual lsd for my 340.... do you know where i should could source that ?
Id love to see some before and after results Ken, amazing job and videos
His name is kevin his channel is kern
@@souljayt8411 relax I know , I follow him on the forums as well, meant to type Kev not Ken
went to the track last weekend and wasn't disappointed. video will be posted in a few weeks
"I do have some motivation" 😂😂😂
Sweet! Looked a lot easier to install than I thought, I have replaced the diff on an x5 f15 40e and that was a nightmare lol
lol yeah knocking out the axles was definitely the hardest part. and removing that rear bolt without pulling the axle is a bit tedious
@@kern417 I want to get a mperf lsd on my 440i down the line, but I always feared the installation since you can’t unscrew the axles from the diff but seeing you do this on jack stands without much issue makes me think doing this on a lift will be a piece of cake
With more space it would be easier for sure
awesome video thanks man! I am contemplating doing this on my N55 F30...I just don't trust a shop lol
Very much looking forward to the review. I'm Borderline at this point. Help me choose
Best mod
I used 2 pry bars to remove my axles from the diff. Took hardly any force, maybe it worked better because it pulls the shaft out square. I also removed the left side control arms to make removing the diff easier.
👌🏾
yay another video ive been interested about for a year now is your 440 on an lsd? dont remember u ever doing this modification
nope it has the stock open diff
@@kern417 I think the real question is, how long will the 440i remain open diff after having another car with an LSD?
@@MrErball 🙃
I just did this to a 2018 340i 6mt at the time of ordering there were two manual LSD's left in stock, one in PA and the other in TX. I guess one of those came to me.
Also when ordering I quoted the price off getbmwparts and got the diff for 2200 and change.
Edited to ask what you did for 'break in'.
Lot's of conflicting info, i ended up doing 20 figure 8's and then 20 circles at idle left and right. I then de-tuned the car back to MPPSK and after 500 miles will give it the full potatoes.
I took it straight to the track 🫣
Got the confidence to do this on my garage floor thanks to your video and also watched it a lot during the install process. Have you already replaced the fluid from the initial "break-in" period? I'm seeing anywhere from 500-1500 miles being recommended.
Yeah they recommend 500mi in the manual
Thais makes me want an m car even more.
Great video! Do you know if the removal/install is the same/similar for the F22 M235i (N55) RWD/Manual platform? I've been looking for a DIY video that doesn't just state that it's not recommended because you don't have BMW's special $800 tool to remove the axle shafts lol. Thanks!
Would love if you could make a video on how to properly jack up the f3x chassis onto jack stands, Super sketch when I do it.
Sure I'll add it to the list
Looks like half of a how to replace the driveshaft video too 😊
😏
Need the xdrive lsd vid
More info on the xdrive lsd setup plz
For stock 340i open diff, do you recommend sticking with OEM BMW Diff oil, or would you say its safe to the run the Redline MT85 GL4 oil? Ive been reading mixed reviews on running the redline oil, but just not wanting to spend the extra money on the OEM BMW oil if I dont have to. Thanks!
oem is fine
Awesome video as always. I have a question, I just bought a 2016 340i that has all the performance parts, however I’m unsure as to if it has an LSD or not. Is there a way to find out?
Google bmw vin decoder and pop your vin in there. It will tell you all the packages your car came with from factory.
@@mkvB58KING That won't show, it was a port or dealer fit option. Best thing to do is go into a dealership and they'll at least be able to tell you if it was done. Other than that jack the wheels up and see if it turns both wheels.
Lift the back of the car put the car in neutral ans spin the wheels if both spin same direction you got lsd
Did you know if it's compatible with B48? Or only for B58?? I've just checked for a mperformance lsd of 235 on my 120i and is not compatible for the rear drive axle. So actually I've installed a Quaife system and is working very good.
you'd have to swap driveshaft and axles from a rwd car
is there any need after installing it to switch off eLSD in car computer or to do something in car settings?
or is it just put it on and thats it?
thank you : )
Ah I forgot to mention. What oil did you put? You should really change oil around 500 miles. The standard BMW Oil gear oil is what BMW recommends. However that’s wayyy to thin specially because the diff get much hotter then the standard open diff. I advise to put Motul 75w140 or even better OS GIKEN LSD oil 80w250. If you run the diff with the standard BMW oil you gonna wear out the clutch pack in 50k miles. So put thicker oil and change the diff oil at least once a year. Specially when tracking the car. Cheers!
plan on sticking with oem
Is possible to do this tipe of work on a xdrive auto f30?
And what trans ratio would i need?
The car now is on rwd mode flashed with xDelete
And i was thinking to remove the front axels and shaft
0:40
Amazing video!! Looks like a totally doable DIY project..
Wouldn't installing an LSD on an xdrive mess up the system? It's my understanding that xdrive can send/reduce power to individual wheel/s, so I don't see why you would want to install it in the first place.
no, it works fine on x-drive. plenty of awd cars come with front and rear locking differentials.
@@kern417 i know the new M340i/M240i are xdrive and have an LSD. I just wonder if installing one on a car that came with an open dif would interfere with xdrive.
Hi @kern416 Today i got fitted M LSD to my M240i manual. All good, but when i am in the gear and let off the gas there is small jerk. Is it normal? Or my ecu need to adjust for lsd??
probably the lockup
Didn't realise the 340's don't have guibo's. Need to get mine replaced as the torque destroyed it lol
Only on the transmission side, not the diff side
I don’t know if you have an answer for this but is it possible on the xdrive g2x platform to code in the 4wd to 2wd like the g8x?
Potentially with an app like xdelete but you'd have to check and see if your car is compatible
Can you release a video reviewing the LSD and comparing it to the Open Diff?
yes
we are patiently waiting@@kern417
Not sure if i missed it in the video. Do we need to do differential fluid after installing lsd?
it comes pre-filled
That propshaft reverse thread on my car was sooo fucking tight how the hell did you do it like it was nothing
The 50mm nut? If so how did you turn it. Im having the hardest time getting it lose especially on jack stands
How long did it take to swap this in?
Just installed my lsd. Wanted to fill up the oil, and I just saw, that it is already filled? 🤔
Yep, but they do recommend changing the fluid after 500mi
So my power goal is 550-600 whp I currently have the tu pump do you recommend the varges gc or pure 800 cast. Later on I will upgrade to fuel it stage 2 hpfp
pure800
Thank you, is it possible to get high 580-600 whp on varges gc and fuel it stage 2 hpfp on e50 because if so that’s all I’m really shooting for? Just wondering before I pull the trigger on gc
Is the manual part number correct? The one I see ends in 87. The one i got also ends in 87. Cant find 88
It is correct, but it's for 3/4 series only. 1/2 series have a different final drive for manual trans. I updated the description to clarify. Hope that helps
@@kern417 ah gotcha. Thanks for the update
Hey I’m looking to get a 2020 540i but I look at the hp compared to a 340i which Is 380 so I wanted to know if they have a gen 2 b58
2020+ has the TU
Any p/n or input for an Automatic XDRIVE?
0:40
I just received my lsd but the whole thing was soaked in fluid. I know they say it’s filled from the factory but is that normal? Do you know what fluid it takes? I’m finding so much conflicting info… some say use the stock g1 fluid others say 75W140. Even the dealerships are telling me different things
It should take 1L of fluid. Were the seals not in the housing properly?
@@kern417 the yellow seals were in the housing but the whole thing was still covered in oil. Do you know the exact fluid type? some ppl say 75w90 (BMW OEM for stock diff) other ppl say 75w140. Even 2 different BMW dealers told me two different fluids.
@@25mrsameerthere is a hole on the top rear side of the Diff. For air do go in and out when it's getting warm or cold, iff the diff doesn't lay in it's normal position, some fluid can go out. 75w140 would be fine, just take a look, that it's allowed for lsd. I am using motul 75w140 and it works fine. Sorry for my bad english
can a bmw lsd be installed on a x-drive? more exactly on a g30 540i.
0:40
You need to code the e-lsd off, or it will intervene!
Trust me, it worked just fine
Anyone able to confirm the part number for the circlips? Not having luck when looking on realOEM for my m240i.
it's in the video description
@@kern417 damnit....sorry and thank you!
@@JB_287 all good
If i buy that same LSD would i be able to fit it on a 328i 2014 ?
Thanks
you will need to swap other driveline parts
does the supra need this upgrade?
I always thought you had to install the prop shaft with some thread lock. Sure bmw do.....
how are you so sure?
Been looking forward to this video for a while, thanks!@@kern417
From what I've read, you're supposed to put on a new 50mm nut from BMW, it has the thread lock already applied. It's supposed to be fully seated within 5 minutes of tightening then the vehicle is supposed to be motionless for 2 hours while it cures.
The nut is attached to the diff. There's nothing to replace and no thread lock to apply.
@JB-eu3zh thats what Ive seen yes.
@kern417 well, I am going based off bmw fitting. Im sure I even saw a vid of it being done at a bmw garage.
can you change the gearing ratio to the manual diff
yes, i may try in the future and post results
you definitely should
can this work for xdrive as well?
0:40
Is there an LSD option for xDrive? Or am I screwed
You cannot use the mperformance option without swapping over some rwd components. But there are other options like wavetrac that you can use to rebuild your diff internals with an LSD
Is the process the same if it’s xDrive? If not how is it different?
the mperformance lsd is not an option for x-drive. you'll need to rebuild the diff with an aftermarket lsd. but to remove and reinstall, the process is the same.
@@kern417 are there people making rebuild kits to convert to lsd? do you think it’ll help for someone chasing better times in the 1/4
Wavetrac, quaife, etc all make them. No I would not expect a significant improvement in quarter mile times.
I have an x drive 6mt 440 can I get a lsd?

Hooooly crap, it’s like you knew I was doing this mod in a few months 😂🤌🏼
